Questions and Correct Answers with Rationale
1. Which activity is an example of primary prevention in community health nursing?
A. Providing influenza immunizations to healthy elderly adults
B. Performing scoliosis screenings at a middle school
C. Leading a support group for individuals with diabetes
D. Teaching a client how to use a walker after a hip replacement
Ans: A
Explanation: Primary prevention focuses on preventing the initial occurrence of a disease or injury.
Administering influenza immunizations is a classic example as it builds immunity before exposure
happens. This level of intervention targets healthy populations to maintain their current wellness status.
It differs from secondary prevention, which involves early detection like scoliosis screenings. By reducing
the incidence of disease, nurses help lower overall community healthcare costs.
2. What is the main focus of a windshield survey?
A. Observing the community’s physical environment while driving through it
B. Reviewing census data to determine population density
C. Interviewing local government officials about budget issues
D. Conducting formal health screenings at a local community center
Ans: A
Explanation: A windshield survey is an informal tool used to gather objective data about a
neighborhood’s characteristics. Nurses use this method to observe housing, transportation, and general
,environmental health while traveling in a vehicle. This technique provides a quick overview of the
community’s strengths and potential health risks. It is often considered the first step in a comprehensive
community assessment process. Understanding the physical context helps nurses plan more effective and
relevant health interventions.
3. A nurse provides rehabilitation services for a client following a stroke. This is an example of which level of
prevention?
A. Primary prevention
B. Secondary prevention
C. Quaternary prevention
D. Tertiary prevention
Ans: D
Explanation: Tertiary prevention aims to minimize the effects of long-term disease or disability through
rehabilitation. In this scenario, the nurse is helping a stroke survivor regain function and prevent further
complications. This level of care focuses on restoration and improving the quality of life for the
individual. It occurs after a condition has been diagnosed and treated in its acute phase. Tertiary
strategies are vital for reducing permanent disability and promoting independence in the community.
4. In the epidemiological triangle, what does the term ‘agent’ refer to?
A. The factor that causes the disease or injury
B. The living being affected by the disease
C. The external conditions surrounding the host
D. The geographical location where the outbreak occurs
Ans: A
, Explanation: The epidemiological triangle consists of the agent, the host, and the environment. The
agent is the specific factor, such as a virus or chemical, that causes illness. Understanding the agent is
crucial for developing targeted interventions to stop disease spread. This contrasts with the host, which
is the person or animal that is susceptible to the agent. Effective public health nursing requires analyzing
how these three factors interact within a population.
5. Which core function of public health involves monitoring health status to identify community health
problems?
A. Policy Development
B. Assessment
C. Assurance
D. Advocacy
Ans: B
Explanation: Assessment is one of the three core functions of public health defined by the Institute of
Medicine. It involves the systematic collection and analysis of data regarding the health of a community.
This function ensures that health problems and trends are identified accurately and in a timely manner.
Once assessment is complete, the data can be used to inform policy and assurance activities. Nurses play
a key role in this function by conducting surveys and analyzing health statistics.
6. A community health nurse is screening school children for lice. This action represents which level of
